Benefits of technology

Yet further, an agonist of PSEQ may be administered to a subject to treat or prevent a disease associated with decreased expression, longevity or activity of PSEQ.

Problems solved by technology

As a result, bones become larger, heavier and denser.
Osteoporosis develops when bone resorption occurs too quickly or if replacement occurs too slowly.

It is to be understood that this invention is not limited to the particular devices, machines, materials and methods described. Although particular embodiments are described, equivalent embodiments may be used to practice the invention. The described embodiments are provided to illustrate the invention and are not intended to limit the scope of the invention which is limited only by the appended claims.

I cDNA Library Construction

The cDNA library, BONTNOT01, was selected as an example to demonstrate the construction of cDNA libraries from which the novel polynucleotides were derived. The BONTNOT01 tibial periosteum library was constructed using 7 nanograms of polyA RNA isolated from tibial periosteum removed from a 20-year-old Caucasian male. Pathology for the matched tumor tissue indicated partially necrotic and cystic ostcoblastic grade 3 osteosarcoma (post-chemotherapy). The tumor involved almost the entire length of the femoral shaft along the site of a previously placed metal ro...

Abstract

The invention provides polynucleotides and polypeptides that are co-expressed with genes known to be involved in bone remodeling and osteoporosis. The invention also provides expression vectors, host cells, and methods for making a polypeptide, for screening or purifying ligands, and for diagnosing disorders associated with bone remodeling or osteoporosis.

Description

The invention relates to 169 genes identified by their co-expression with genes known to be involved in bone remodeling and bone diseases. The invention also relates to the use of these genes and their gene products in diagnosis, prognosis, prevention, treatment, and evaluation of therapies for bone diseases such as osteoporosis.Bone RemodelingBone remodeling occurs through teams of juxtaposed bone absorbing osteoclast and bone forming osteoblast and osteocyte cells. The development and proliferation of these cells from their progenitors is governed by networks of growth factors and cytokines produced in the bone microenvironment as well as by systematic hormones (Manolagas (1998) Aging 10:182-190; Teitelbaum et al. (1997) J Leukoc Biol 61:381-388). Coordinated balance between absorption and deposition is necessary to maintain bone integrity and requires intimate and complex interactions between osteoclasts and osteoblasts. Under normal states of bone homeostasis, the remodeling act...
